REED-DENT-SEPA RATING DEVICE FOR WARP-DRAWING MACHINES.

$PECIPICATION forming part of Letters Patent No. 363,689, dated May 24, 1887.

Application filed March 17, 1887. Serial No. 231,263. (No model.)

a side view'of a warp-drawing machine with my improved dent-separating device. Fig. 2 is a perspective view of my improved reeddent separator detached from the machine. Fig. 3 is a section on the line 1 2, Fig. 2. Fig. 4 is a perspective view showing part of the reed, the dent-separator, part of its operating mechanism, and part of the drawing-needle; and Fig.,5'is a View, partlyin plan and partly in section, showing the dent-separator and part of the reed and needle.

The warpdrawing machine illustrated in Fig. l is fully described in the Patent No. 355,221, dated December 28, 1886, and.therefore need not be described minutely.

A is the bed of the machine, supported on suitable legs, a, and having guides to which is adapted the traveling carriage or slide B, the latter being fed from right to left by means of a feedscrew, O, driven from the main shaft D of the machine.

S is the needle-casing, secured to the earriage B, and z the needle, which is drawn into and projected from the casing S by mechanism l'ully set forth in said prior patent, the needle being preferably a flat steel bar, as shown in Fig. 4.

Attached to the back of the frame A are.

brackets a, 011 which are the-posts e e, for supporting the cross-bars c, carrying the hedtiles, and on the outer ends of the brackets a selecting device, which separates a thread from the series on the frame F and places it in the path of the needle, as fully described in the patent referred to above.

The reed-dent-separating device comprises simply a disk, M, having a flange, Q, with overlapping ends at m, the flange being free from connection with the disk for some dis tance from its end an, so that the ends can be sprung apart from each other to any desired extent by means of the set-screw a acting on said free end of the flange, as shown in Fig. 3. The end at of the flange 'is thickened or expanded laterally, so that when it is inserted between two of the dents of the reed it will spread said dents apart and facilitate the passage of the needle through the space between the dents.

The disk M is secured to a short shaft, q", having its bearings in an arm, Q, hung to a stud on the casing S. The arm Q, is pivotally secured to the stud on the casing S by means of a set-screw, b, Fig. 1, in order that the reedseparator can be thrown up away from the reed and out of gear with -the machine when desired.

On the shaft 1 is a bevel-wheel, g", which gears with a bevel-wheel, q, on a short shaft,

q, this shaft having a pinion, p, which engages with a segment gear-wheel, p, on a shaft, I, the latter being geared to an upright shaft, J, which in turn is geared to a horizontal shaft, I, by. a worm, i, and worm-wheel z", the shaft 1 deriving its motion from the main shaft D through the medium of spur-gears d and h, shaft H, and bevel-gears h and i, as will be seen on reference to Fig. 1. The segment gearwheel 1) serves to impart to the shaft q rotary movements with intervening periods of rest, as will be readily understood.

The flange Q acts as a screw-thread, the for ward end of the flange entering space after space between the dents of the reed G in succession as the disk M rotates, and the movement of the dent separator is arrested at that 9 5 IPO The lateral adjustment of the end of the flange Q by means of the set-screw it serves to adapt the dent-separator to reeds of different gages.

By the use of the reed-dent separator described, friction 011 the needle is reduced and the skipping of any of the spaces is prevented.

I claim as my invention- 1. The combination of the reed holder and the reciprocating Warp-drawing needle with the separator-disk and with mechanism whereby the same is intermittingly rotated, all substantially as specified.

2. The combination of the reed-holder, the reciprocating warp-drawing needle, the intermittin'glyrotated separator-disk, and the slide or carriage on which said needle and disk are mounted, all substantially as specified.

3. The within-described reed-dent separator for warp-drawing machines, the same consistingot a disk with a flange forming asection of ascrew-thread, one of the ends of said flange LEWIS P. SHERMAN.
